Count Duplicates in a List Online Tool
This online utility quickly aggregates the lines pasted in the text box and shows you count of occurrences of each value. Use this to quickly aggregate the values to find duplicate lines, or to count the number of repeats.
If you have an Excel spreadsheet and want to get distinct values from a column, just copy and paste the column of data from your Excel sheet into the textbox below. You will get a list of the unique values along with the count of occurrences for each value.
Paste your text in the text box and then press the "Display/Update Counts" button.
Data entered into the form above is processed client-side in your web browser, and is never sent or stored anywhere besides your device.
New CSV output format option allows you to copy and paste the results into Excel or LibreOffice Calc in a spreadsheet format.
CSV output is in Excel-compatible format, with comma as the separator, and double-quote as the enclosure and escape character.
After copy-pasting in to Excel, use the Data > Text to Columns to split the text into columns. Alternatively, save the data using Notepad to a file ending with ".csv", and then double-click the file to open it in Excel automatically.
